Unfired clay masonry: An introduction to low-impact building materials
BRE (Building Research Establishment) is an independent, research-based consultancy, testing and training organisation, operating in the built environment and associated industries.
Unfired clay masonry: An introduction to low-impact building materials, was written by A Sutton, D Black and P Walker and published by BRE on 18 October 2011.
It is one of a series of five information papers and case studies about low-impact building materials, which also cover; hemp lime, straw bale, cross-laminated timber and natural fibre insulation.
In comparison with some alternative construction products, unfired clay masonry is relatively low-impact, and it has one of the longest histories of use of any building material. It is relatively robust, fire-resistant, has high thermal mass and has the capacity to moderate internal humidity levels. However, unless stabilised, it is not resistant to prolonged water exposure and so it normally requires protection from rain.
This 6-page information paper provides an overview of the pros and cons of non-loadbearing unfired clay brick and block. It is intended for those considering the use of this material on construction projects.
